My first chicken in a while, a Cochin, laid her first egg, but it was on top of a wall in a nest she had made. I wanted her to lay in a nest box, so when she went onto the wall to lay an egg, I moved her to a nest box and blocked off the opening so she would not get out. After an hour, she still had not laid an egg, and when I let her out, she went straight to her nest on the wall and laid her egg. I removed the ladder she used to go up the wall after she laid her egg. Is their any way to train her or my other pullets (not yet laying) to lay in the nest box? Thank you.
